  Wireless communication evolves from generation to generation by developing various key technologies, strategies, and principles to handle challenges arising therein. The dramatic growth in the number of smartphones, tablets, wearables, and other data-consuming devices, coupled with the advent of enhanced multimedia applications, has resulted in a tremendous increase in the volume of mobile data traffic. According to industry estimates, this increase in data traffic is expected to continue in the coming years and around 2020 cellular networks might need to deliver as much as 100-1000 times the capacity of current commercial cellular systems [1]. Therefore the attention of the mobile research community is now shifting towards what will be the next set of innovations in wireless communication technologies, which we will refer to collectively as 5G (fifth-generation technologies). Given a historical 10-year cycle for every generation of cellular advancement, it is expected that networks with 5G technologies will be deployed around 2020 [1]. The 5G networks will consist of different network elements but still as in the previous cellular technologies the base station is the main important node with many tasks and responsibilities. In the paper we discuss the main requirements of next generation (5G) base stations and emphasize the design challenges set by new 5G technologies. 2. 5G USE CASES AND MAIN REQUIREMENTS AND CHALLENGES FOR 5G RADIO NETWORKS It is envisioned that new technology and future services will have significant influence on societies, transforming the ways they function. Exact services and ways are not defined and most of them are to be invented in coming years. Yet, we can try to imagine which drivers and demands will have impact on development of these services and use cases. Therefore, telecom community is making an effort of categorizing and defining most probable future use cases in order to properly addre[...]
